PEN-W IPER.

Patented Nov. 20, 1906.

Application filed December 1, 1905. Serial No. 289.926.

To J/ZZ whom it may concern.-

Be it known that I, CARL F. RIGHARD STUPE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, haveinvented new and useful Improvements in Pen-Wipers, of which the following is a description.

My invention relates to a device for wiping or cleaning pens and also, when desired, for removing them from their holders without danger of soiling the hands or clothing.

The object of my invention is to provide a neat, inexpensive, and convenient device of the kind described in which the wipers may be made to grip the pen with any desired pressure, even of that required to extract the pen from the holder under ordinary conditions, if desired.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar reference characters indicate like or corresponding parts, Figure 1 is a section taken substantially on line 1 1 of Fig. 2. Fig. 2 isa plan view of my device with the cover removed. Fig. 3 is a section taken substantially on line 3 3 of Fig. 1, and Fig. 4 is a detail showing a preferred method of securing the wiper-pads to the arms.

In the preferred form of my device shown in the drawings, 1 is a rectangular frame or base provided near one end with two similar and substantially vertical arms or fingers 2 and 3. The arm 2 is preferably rigidly mounted upon the base 1 and, as shown, is of sufficient length to project slightly beyond the remaining portions of the device. The arm 3 is arranged to move longitudinally of the base 1, and for this purpose in the form shown is provided with a foot 4, mounted upon ways or guides 5 and 5. The rods 6 and 6 are also provided substantially parallel to the ways 5 to assist in directing the movement of the foot 4 and also to carry the the foot 4 and arm 3 away from the arm 2, thus normally maintaining the arms 2 and 3 slightly separated.

Any suitable means may be provided upon the adjacent faces of the arms 2 and 3 for removing ink or other material from a pen or As shown, pads 8 and 9 are mounted at the upper ends of the arms 2 and 3, respectively, and suitably formed to cooperate to grasp a pen between them, and thus simultaneously wipe both its concave and convex sides when the pads are forced together.

In the form shown each pad is faced with felt or other suitable material to readily absorb moisture and also sufliciently soft and yielding to prevent injury to the article being wiped. If desired, these pads may be formed integral with the arms 2 and 3 or attached thereto in any desired manner. As shown, each pad is provided with a projection formed to engage a corresponding groove 10, formed in the arm, so that the position of the pad may bereadily adjusted or the pad removed when desired and a fresh pad substituted.

Any suitable means may be employed for controlling the position of the arm 3. As shown, a part 11 is provided upon the foot 4, having an inclined cam-face 12. A similar part 14, having a face 15, is rigidly mounted upon the frame 1 opposite the part 11.

A lever 16 is pivotally mounted upon the frame 1 at 17, and a part 18 is ivotally at tached to the lever 16 at 18, witfi its free end positioned between the parts 11 and 14 and so formed that its downward movement will force the foot 4 and arm 3 toward the arm 2, a stop 19 being provided to limit the movements of the lever and a spring 20 to normally maintain the lever at the upper limit of its movement, so that the arms 2 and 3 and pads 8 and 9 are separated.

In the form shown the lever 16 forms a cover or closure for the frame 1 and is provided with an opening 21, through which the arms 2 and 3 protrude. While the mechan ism shown and described for moving the arm 3 operates very satisfactorily, it is obvious that the parts may be greatly modified and even entirely different mechanism employed for this purpose with equally satisfactory results. Hence I do not wish to be understood as limiting myself to the exact form and construction shown.

To operate my device, the pen or other ob ject to be dried or wiped is held in the proper position between the pads and the cover 16 of my device depressed sufliciently'to bring the pads into suitable contact with the pen,

which is then withdrawn without releasing the pressure of the pads upon the pen.

Obviously if sufhcient pressure is exerted ,upon the lever 16 the pads may be made to apart and a cam member'for moving one of said arms to control the distance between said pads.

2. A device of the kind described, com prising a frame, a stationary and a movable arm mounted upon said frame, a pad provided upon each arm, and means for resiliently forcing said pads apart, in combina tion with a cam member for controlling the position of said movable arm to force said pads together.

3. In a pen-wiper of the kind described, a frame, a stationary arm provided with a wiping-pad mounted near one end of said frame, and a stationary cam mounted near the opposite end of said frame, in combination with a movable arm provided with a wiping-pad, a cam attached to said arm, and

a part for simultaneously en aging said cams to control the position of said movable arm. 4. A pen-wiper of the kind described, comprising a frame, and a stationary arm provided with a wiping-pad, and a stationary cam mounted upon said frame, in combination with a movable arm provided with a wiping-pad and a movable cam mounted upon said frame, resilient means tending to separate said arms, and means simultaneously engaging both of said cams adapted to separate said cams and force said arms together.

5. In a pen-wiper, a frame, a stationary wiping-arm mounted near one end of said frame, and a stationary cam mounted near the opposite end of said frame, in combination with a movable coo erating wi ing-arm, a guide for said movab e arm and resilient means tending to normally force the movable arm toward the end of the guide opposite the stationary arm, and a cam member adapted to cooperate with said stationary cam and the movable arm to control the distance between the said stationary and movable wiping-arms.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
